I'll try the suggestions you sent. regarding the esp -- iI foirgot to mention that it also crashes when I unplug the connection from a router and reconnect to the E2864i. it even sometimes crashes when somebody calls in (e.g. faxes are received) or if I push the front switches that emit data to the esp card. weird. note that I use OSS drivers, not builtin sound. maybe an option to check out too. to me it sounds like corruption in memory that causes the crash. -- Grobbebol's Home | Don't give in to spammers. -o) http://www.xs4all.nl/~bengel | Use your real e-mail address /\ Linux 2.2.16 SMP 2x466MHz / 256 MB |on Usenet. _\_v - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Well that surely shouldnt happen...I use minicom all the time (I still call BBSes), and havent had any crashes. I can quit/disconnect, or quit/stay connected and it works okay. I've even got it set up to use 23bps, which is the max my Zoom will take. When I was trying to set up the ESP shortly after I'd received it, there was some trial+error to get the address/irq/dma/jumpers set right, and minicom would hang (the program), but I could kill it. It took about an hour to get the settings the way I'd wanted them, and since then... no real problems. > I do not use the DMA channel of the card as it conflicts with the SB16 I > have on board. I also have a SB16 (non-PnP). I use DMA 1 and 5 for the SB16 and 3 for the ESP.I dont know if it's doing anything though...wish there were a way to know how deep into the buffers it ever gets on transfers. DMA threshold on mine is the default value (I believe it's 32 bytes) -- it wouldnt suprise me if it didnt get that deep, keeping the rx_threshold so low. My modules.conf ESP section looks like: # # Hayes ESP module + options # port 180h, irq 3, dma 3, divisor 4 options esp irq=0,0,3,0,0,0,0,0 dma=3 divisor=0,0,0x04,0,0,0,0,0 rx_timeout=1 post-install esp setserial /dev/ttyP16 low_latency alias char-major-57 esp alias chat-major-58 esp Only troubles it's given me lately is that esp.c isnt a devfs-aware driver. I've been experimenting with devfs lately, so I have to do a "mknod /dev/ttyP16 c 57 16" every time I boot, and it still barks out a few meaningless errors (cup: device already registered). I just have the one-port ESP card. -- Mark Orr [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

I havent had any crashes or hangs related to it, but I dont use mgetty. (I use rungetty, a variant of mingetty, for VC's).Seeing this, I will compile up mgetty here to see if I can replicate it. (once in a while, communications becomes non-responsive -- but I suspect that it's just my Zoom modem, which clams up for no apparent reason. The port seems to be doing it's thing.) > the IRQ is 11, not using DMA, IRQ is set to legacy in the BIOS. > it happens with any 2.2.xx version and also happens with 2.4.0. I'm running 2.4.0-ac12 here. ESP is set to 180h, IRQ 3, DMA 3. (I disabled my onboard serial ports). CPU is a classic Pentium. I've been running it w/ rx_timeout=1 (the minimum usable value, since it seems to give lower ping times) Got this ESP off eBay -- in fact, I got it after reading Mr. Jansen's recommendation 2 years ago in the comp.dcom.* groups (probably ISDN), noting how flexible and tweakable the ESP drivers are. FWIW, I was getting mountains of TCP errors before I got this card, and they all disappeared once I installed the ESP. It's an amazing card. -- Mark Orr [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
